Abstract

Purpose: The aim of our study was to investigate the roles of cerebral perfusion pressure (CPP) and microdialysis marker values on the clinical outcome of patients with spontaneous intracerebral hematoma.

Materials and methods: Twenty-seven patients (18 men; mean ± SD age, 54.17 ± 10.05 years; 9 women, mean ± SD age, 65.00 ± 4.24 years) with a GCS of 8 or less upon admission were included in this study. After a 6-month follow-up period, a linear regression model was applied to evaluate the outcomes using the Glasgow Outcome Scale (GOS).

Results: Of the 27 patients, 16 died within the first 6 months after discharge from the hospital. Six patients had a favorable prognosis after 6 months. In the patients who had a favorable outcome (GOS = 4 or GOS = 5), the CPP was above 75.46 mm Hg, and intracranial pressure was below 14.21 mm Hg. No patient with a favorable prognosis had a lactate-pyruvate (L/P) ratio greater than 37.40. An inverse linear relationship was found among the L/P ratio, the CPP, and patient outcome.

Conclusion: The L/P ratio and CPP were found to be related to patient outcome. In addition, a CPP greater than 75.46 mm Hg and an L/P ratio lower than 37.40 mm Hg were related to a favorable outcome.
